21312262 ÷ 507 
We're looking to find how many times 507 goes into 21312262.

Step 1:
507 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 507

Advancing to step 2:
The number 507 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 507

Step 3:
507 can be fit into 213 0 times, resulting in a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Grab the next digit (1) from the dividend, add it to 213, then carry on: 2131 / 507

Moving on to step 4:
When dividing 2131 by 507, we get 4 with a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2028 from 2131 to get 103.
Grab the next digit (2) from the dividend, add it to 103, then carry on: 1032 / 507

Advancing to step 5:
507 goes into 1032 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 1014 away from 1032, we end up with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 507

Going ahead to step 6:
The number 507 fits into 182 0 times, leaving a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 420.0
Deduct 0 from 182 and we're left with 182.
Bring next digit (6) of the dividend behind the 182 and repeat the process: 1826 / 507

Advancing to step 7:
1826 divided by 507 is 3 with a remainder of 305.
Record the quotient 3 as the next digit in the result. 
Result so far: 4203.0
If we take 1521 away from 1826, we end up with 305.
Append the next digit (2) from the dividend to 305 and continue with: 3052 / 507

Moving on to step 8:
The number 507 fits into 3052 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 42036.0
Subtracting 3042 from 3052 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 507 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 42036.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
The number 507 fits into 1000 1 times, leaving a remainder of 493.
The next digit of our result is 1. 
Result so far: 42036.01
Subtract 507 from 1000 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 11:
507 goes into 4930 9 times with a remainder of 367.
The number 9 becomes the next digit in our result. 
Result so far: 42036.019
Subtracting 4563 from 4930 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 12:
507 can be fit into 3670 7 times, resulting in a remainder of 121.
Record the quotient 7 as the next digit in the result. 
Result so far: 42036.0197
If we take 3549 away from 3670, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 13:
If we divide 1210 by 507, we get 2 and a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 42036.01972
Subtract 1014 from 1210 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
The number 507 fits into 1960 3 times, leaving a remainder of 439.
The number 3 becomes the next digit in our result. 
Result so far: 42036.019723
Deduct 1521 from 1960 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 15:
When dividing 4390 by 507, we get 8 with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 42036.0197238
If we take 4056 away from 4390, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 16:
The number 507 fits into 3340 6 times, leaving a remainder of 298.
Put 6 as the next digit of the answer. 
Result so far: 42036.01972386
If we take 3042 away from 3340, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The final result is 42036.01972386 with a remainder of 2.98e-07.
